It’s a battle of the blondes! Who do YOU think looked hotter?

Jennifer Aniston turned up the heat at the March 11 premiere of The Bounty Hunter in London, showing off her killer legs in a tight sparkly silver mini — but she’s not the only blonde we’ve seen in a dress like that recently. Jessica Simpson – who will be appearing alongside Jen on Good Morning America 15 – strutted her stuff in a similar outfit at the after party celebrating little sis Ashlee‘s November debut in Chicago on Broadway! Which blonde pulled the look off better, Jen or Jess?
